Reimplement shared library support on ppc-aix...
... using the target_so_ops framework. gdb/ChangeLog: * target.h (TARGET_OBJECT_AIX_LIBRARIES): New target_object enum. * features/library-list-aix.dtd: New file. * solib-aix.h, solib-aix.c: New file. * rs6000-aix-tdep.c: #include "solib.h" and "solib-aix.h". (rs6000_find_toc_address_hook): Delete. (rs6000_push_dummy_call): Rewrite code setting the TOC value. (rs6000_aix_init_osabi): Register solib_aix_so_ops. * rs6000-nat.c: Remove "xcoffsolib.h" include. Include "xml-utils.h". (map_vmap, vmap_exec, vmap_ldinfo, add_vmap, objfile_symbol_add) (vmap_symtab, fixup_breakpoints): Delete. (rs6000_xfer_shared_libraries): New function. (rs6000_xfer_partial): Add TARGET_OBJECT_AIX_LIBRARIES handling. (vmap_secs, bss_data_overlap, vmap_add_symbols): Delete. (xcoff_relocate_symtab, xcoff_relocate_core): Delete. (rs6000_ptrace_ldinfo, rs6000_core_ldinfo) (rs6000_xfer_shared_library): New function. (find_toc_address): Delete. (_initialize_rs6000_nat): Do not set rs6000_find_toc_address_hook. * rs6000-tdep.h (rs6000_find_toc_address_hook): Remove. * xcoffread.c (record_minimal_symbol): Reloate symbol address before creating minimal symbol. Adjust function description accordingly. (scan_xcoff_symtab): Replace call to prim_record_minimal_symbol_and_info by call to record_minimal_symbol. (xcoff_symfile_offsets): Reimplement mostly as a wrapper around default_symfile_offsets. * configure.tgt: Add solib-aix.o to gdb_target_obs for powerpc-aix targets. * config/rs6000/nm-rs6000.h: Delete. * config/powerpc/aix.mh (NAT_FILE): Delete. (NATDEPFILES): Remove xcoffsolib.o. * Makefile.in (XMLFILES): Add library-list-aix.dtd. (ALL_TARGET_OBS): Add solib-aix.o. (HFILES_NO_SRCDIR): Remove xcoffsolib.h and config/rs6000/nm-rs6000.h. Add solib-aix.h. (ALLDEPFILES): Add solib-aix.c. Remove xcoffsolib.c. * xcoffsolib.h, xcoffsolib.c: Delete. * solib.c (reload_shared_libraries): Remove reference to SOLIB_CREATE_INFERIOR_HOOK. * breakpoint.c (handle_solib_event): Remove reference to SOLIB_ADD.
